Orange SealEndurance Formula Tubeless Bike Tire Sealant | Long Lasting, Fast Sealing | for MTB, Road, CX and Gravel Bicycle Tires

I had two flat tires on my mountain bike, so I tried this before I was going to replace them and it worked perfectly. They both had slow leaks, and as soon as I would fill them up with their like an hour later, they would be deflated and after using this stuff, it’s been almost a week and the tires are still filled!

Had used another brand for some time, and switched after not being entirely satisfied. Not going back! This is a great sealant and does the job very well, sealing punctures quickly. Lasts for awhile and doesn’t clump in bottle. This is the tire sealant you’re looking for. Pro tip: always add double what’s called for.

One of the best two sealants on the market along with Silca’s.

This stuff works great. I ride in the high desert in Southern California and goat head thorns have been the bane of my existence ever since I started cycling. I tried Slime and tire liners. Slime works sometimes but just leaves a mess with bigger thorn holes, and even plastic tire liners are no match for a strong goat head. Ever since switching to this stuff, I've barely had to think of thorns. Maybe stop every once in a while to pull some out of my tires and keep riding.Don't know if its the seller or Amazon, but the shipping lately has been taking way too long. It's listed as Prime Next Day shipping and says that when buying but then switches to two weeks. I bought one and saw that and cancelled to order a different size that said I would get it the next day, then that one also changed to two weeks. I'm paying for Prime so things that say next day ship next day.

Low pressures in MTB bikes mean you can use the thinner sealants. But if your riding gravel or road bikes you need something that seals at higher tire pressures. A thin sealant is designed to work at 20 psi or less. It just sprays out of my gravel tires at 35-40 psi. So, I tried Orange and it works very well. I use the regular formula to setting up new tires with those seeping sidewalls. Then, I use the endurance formula for refills. It also seems to last much longer than the regular formula. Of course that sidewall seeping is really about how supple your tires are. Anyway, I use different sealants and always use Orange in gravel/road tires.

I'm always leary when I order "only 1 left", not knowing if I'm going to receive a quality item, or a "this is what we had left" not quite all there item. The Orange Seal came as described, and I expect to continue having no-flat rides.

this stuff works great and smells good

Put this in my family’s tubes 6 bikes, we literally haven’t had a flat to repair since. It still hasn’t dried out. That was almost 3 yrs ago. In fact we’ve had to replace tires from lack of tread since but no flats. I bought two of the 32oz bottles, it’s time to restock. Great product.
